Abstract (en)
[origin: US5336039A] A load-handling parallel arm clamp structure for a lift truck comprises a slide guide frame having respective upper and lower pairs of elongate, parallel, vertically-spaced transverse slide guides with load-arm supporting slide members longitudinally movable thereon alternatively toward or away from one another in a mutually overlapping longitudinal relationship. Each slide member at least partially surrounds the respective slide guide upon which it is mounted, and each slide guide in turn at least partially surrounds a respective piston and cylinder assembly for moving the slides relative to the guides. The upper and lower pairs of guides are separated by a wide, unobstructed central vertical space through which the operator can view in a forward direction, such space being unoccupied by any view-impeding piston and cylinder assemblies due to their placement inside the guides. A compact fluid manifold and valve arrangement for controlling the piston and cylinder assemblies, together with the space-saving cylinder-enclosing slide guides, minimize the thickness of the entire assembly in the forward direction to maximize load-carrying capacity compatibly with the high degree of operator visibility provided.
